Specific embodiment
Below in conjunction with attached drawing, the present invention will be further described.
As shown in Figure 1, during system normal operation, operated pneumatic valve is real by the energization or power-off of two-position-five-way solenoid valve
Existing valve opens or closes operation；
When needing fast operating operated pneumatic valve in special circumstances, two-position-five-way solenoid valve 2 and two two two energization magnetic
Valve works at the same time, and makes valve cylinder fast aeration or deflation, realizes the purpose for quickly opening or closing operated pneumatic valve；Specifically exist
When needing quickly to open, two-position-five-way solenoid valve 2 powers off, and manipulates first blow vent 21 of the air source by two-position-five-way solenoid valve 2
Cylinder, which is entered, with the second blow vent 22 opens chamber 7, while manipulate air inlet 31 of the air source by the one or two two three-way electromagnetic valves
Enter cylinder with the one or two two three-way electromagnetic valve gas outlets 32 and open chamber 7；The gas that cylinder is closed in chamber 6 passes through two-position five-way electricity
23 and the 4th blow vent 24 of third blow vent of magnet valve 2 is discharged, while pass through 41 He of air inlet of the two or two two three-way electromagnetic valves
It discharges two or two two three-way electromagnetic valve gas outlets 42；When needing quick closedown, two-position-five-way solenoid valve 2 powers off, and manipulates air source
Cylinder is entered by the first blow vent 21 and the second blow vent 22 of two-position-five-way solenoid valve and closes chamber 6, while manipulate air source
Pass through the air inlet 31 and the one or two two three-way electromagnetic valve gas outlets 32 entrance cylinder closing chamber 6 of the one or two two three-way electromagnetic valves；
The gas that cylinder is opened in chamber 7 is discharged by 23 and the 4th blow vent 24 of third blow vent of two-position-five-way solenoid valve, is led to simultaneously
The air inlet 41 and the two or two two three-way electromagnetic valve gas outlets 42 for crossing the two or two two three-way electromagnetic valve are discharged；Two-way air source simultaneously into
Enter cylinder, realize fast aeration and deflation.In the entrance of two two two three-way electromagnetic valves, throttle can be set, it can be by adjusting
The circulation area of throttle adjusts switching speed of pneumatic valve, prevents from opening or closing too fast, leads to system surge pressure mistake
Cause system destruction greatly.
In liquid oxygen supply system the present invention is applied in China model liquid propellant rocket engine test platform DN600, if
The low temperature pneumatic stopping valve that nominal diameter is 600mm, design pressure is 1.6MPa is put.During liquid oxygen system normal operation, the valve
Door is manipulated by two-position-five-way solenoid valve, and the opening and closing time is 8s, but when being in an emergency, and needs quick closedown
The valve.By above-mentioned control mode, the operated pneumatic valve most fast shut-in time is made to be decreased to 1.4s, while by adjusting throttling
Circle, can adjust the time that valve opens or closes to 1.4s~8s, using effect is good, meets testing stand to this
The particular/special requirement of operated pneumatic valve control.
